The 144-piece silver commemorative set includes all of the 50 different type coin commemoratives issued from 1892 through 1954, plus each date and mintmark of the multiple issues. For instance, there was only one York commemorative issued, but there were three Cincinnati commemoratives (1936-P, 1936-D, and 1936-S) and 13 different Texas commemoratives. This popular series is filled with low-mintage coins, including the lowest mintage silver coins of the 20th century. Most commemoratives are mint state, as they are what is called NCLT, or non-circulating legal tender. Key issues of the series are the Hawaiian, Hudson, and Spanish Trail (low mintage type coins) and the Sesqui and Monroe (condition rarities), plus the Lafayette dollar among many others.
